To all whom it may comm.-

Be it known that I, ALBERT DAY, a subject of the King of Great Britain and Ireland, residing at 21 Hartley avenue, Leeds, in the county of .York, England, have invented new and useful Improvements in Packaging-Ma-- chines, of which the following'is a specifica- This inventlon relates to improvements in the machine described chiefly in the specifi cation of United States of America Letters Patent granted to me on the seventeenth day of November 1903, No. 744,172. In the machine described-in. the said .rior'specification, a number of'bottomle'ss oxes traverse a rectangular. track between "guides, being moved intermittently by plungers at the corners of the track. Bags are placed in the boxes, and receive their contents from a chute, being shakenby a vibrating plungel beneath them. They are next rammed by a plunger and again shaken at the next station.

.- used for, say, dig

A creasinglate next descends'onto the contents, and t e front of the bag is folded-down over it by a plate, the hinge pin of which can work ina vertical slot. The creasing-plate rises, and the bag moves to the next station, where the back flap is folded'downby another hinged plate, "and the front fia is folded down again by a horizontalsiide, whichv passes between and o ens the side flaps, and then these are folded down by two blades, which are uided b pins in curved cam slots. The irox is a justed at this station by a centering-fork. At another station the acketis pressed by ,a vertical plunger, an. finally, it is pushed/through a ole 1n the bottom of the track'by a plunger folds of what may be termed a square bag, 'such as is used for, say, tea, instead of the folds of the rectangular bag, such as-is soap, and which is described in the sai specification, and second, to provide means for more efficiently depositing and laying the cards in such square In the drawings hereunto annexed I have only shown such portions of the machine described and illustrated in the said specifica tion as are necessary for applying this invention thereto.

Like arts mall the views are marked with similar otters of reference.

In the resent invention, thatis, in what is termed t e square ba ,'-th e end of which is shown at' Fi '1, the ont ortion 5 of the mouth of the ag is first folded, then the two sides 6, 7, are separately closed over the front portion, which causes the back portion 8 to assume a pointed or triangular form before being closed over.

The main features of this machine are of a similar construction to that described in the said prior specification, except as hereinafter mentioned. 1

A is'the framework of the machine upon which is mounted the table it. 'The framework A and table h at Fi 2 and 3 are shown in dotted lines. Uponit e table h is mounted the rectangular track formed of guides b and hereafter termed the guide trough b.

In the said'guide trough b a number of botand the ends of the-bag are operated upon and its folds formed as hereinafter described. Motion is communicated to the several above named operative parts by means of cams,mounted upon shafts, gearing and chains.

H is a chute through which the mat-erial'is assed into the bag in one-of the traveling oxes.

Accordin to this invention the slotted plate provlded with lugs and termed a folder which is described in the said prior specification as being mounted to the rear of t e longitudinal portionof the rectangular. guide trough b so as to work over the same in conjunction with the side folders, is.dispensed with and in place thereofa block a is provided with itsfront face made to incline awa fromthe top of the traveling box 0 wor g the guide trough b, that is, the face is, inclined from bottom to top, as shown at Figs. 4 and 8, while its sides are at or without the addition of adjust machine.

about a right angle with the guide trough b. The inclined faced block a is mounted by bosses upon rods d fixed to the side of the trough b. Thesaid rodsform bearings so that the said block is capable of receiving a short intermittent reciprocating motion from some rotatingpart'of the machine bymeans of, say, a cam e -mounted on the driving shaft of'the machine, double ,ended lever f. fulcrumed,tq a. bracket 9 fixed to the ui1derside of the table h, and an adjustable link 'i.

The two side'folders 7', 7c, are jointed fl .hith-' erto to horizontal rods-l, m,n ounted in suitable bearings,c apable of being sepa. rately intermittently reei rocated from some' rotating part of the mac e, say, the cam shaft 11. by means of two carnso, with or 3%16 links. In the drawings the ad'ustable links are shown dispensed with. he side folders k, are also moved inwards, that is, towar s each other, by cam' grooves or aths q, r, fixed to, say, the top of the tab e h of the he cam paths are of asimilar construction to those described in. the hereinbefore mentioned specification: The side folders are provided with suitably shaped ends as shown, that is tosay, they are curved and inclined as shown a't-F gs. :4 ahd 5, while their inner faces (Fig. 5) are at or about a right angle-with'the trough b, and their under surfaces are made flat. The movement of the said folders isso timed that at one portion of their action they are moved outwards and inwards simultaneously, as at Fig. 5, for, say, creasing purposes, and at another stage, say, for folding or .closing the sides 6, 7-,over separately and at different times, as at Fig. 9. But when the two folders j, k, are moved at different times it'will be under stoodthat when the folder 70 has been moved into a similar osition to folder as shown at .Fig. 9, the b ock a will also e moved inlarform shown at 1 for preventing the said fold afterwards flying open. occasioned by the shaping and timing of the cams 0, p, as shown at Figs. 4 and 6. One or both of the side folders may he provided with suitably shaped projactions-say, curved, asshown at Figs. 4, 5, and .-),for causing the back upstanding porLion S of the bag to be pressed into the space provided by the inclined face of the first named block a, for what is termed opening the back so as to insure the sides 6, 7, of the mouth being properly folded and creased, thereby reducmg the liability of the back fold 8 being crumpled instead of accurately folded.

. The horizontal plunger t described in the aforesaid' prior specification as a side This difference in the movement is opener-is still mounted on a horizontal rod .v so as to slide in suitable bearingafixed on the table h between the rods Z, m, of the side folders 7', 7c, andit is actuated by a separate cam u mounted upon the cam shaft 7. The

end.of the said plunger )5 reciprocates over a named two side faces that the side folds 6, 7, i

are creased and nipped, that is, when the blocks a and t are in the position shown at' Fig. 8.

and two sides 6, 7 ,-have been closed over, as

above described and the back f0ld.8- made .by the prior foldin s to assume the triangu- 1, the bag is made to.-

travel'forward in an with the box 0 bv the" plunger C under the bar w, which is emp oyed keeping the three previously folded portions-5,6, 7, of the bag in their respective closed ositions. At this stage of the fold- 'ing an closin operations the back fold 8 is.

in an upstan ing position and travels for'- wards with its box 0 on the inner longitudi nal side or edge of the bar w (Figs. 11 and 12) .until it reaches the end of the side ofthe rectangular trough b. The bar w is fixed-to the end or transverse tangular uide trough so as to ro'eeta' suitable distance from and over t e ones in its lon itudinal portion. is carrie tion between the edge of the bar u an of the projection 13,fixed 'to one of the ides or ends of the end stamper 12, until the front ortion of its carrying box 0 is in contact with the outer side of the transverse portion of the rectangular guide trough 9. Theboit c is then in a position to be acted upon by the plunger Z. As the plunger Z pushes the box 0 along the said transverse portion 9 towards the end stamper 12,the upstanding fold 8 is first moved away from the bar w and-as it ortion9 of the rec- After the last named three folds, front 5- The back fold 8" forwards in its upstandin posiscenes partially turned over the folds 5, 6, 7. hen the partially folded end of the bag in the traveling box 0 has been traversed under the end stamper 12, the latter is caused to descend for finally pressing and closing fold 8 in position on to the bag. The box 0 with the completely folded bag therein is then ready to pass to the ejector 25, which takes place when another box centers the transverse portion of the rectangular guide trough 9 and is acted upon by plunger 2.

The traveling boxes 0 in this invention are retained in the main or longitudinal portion of the rectangular guide, throu h b by any suitable form of automatic chec ing device, such as for example, say, a spring pin at working in a tube or carrier y fixed to the end of the trough near to its transverse portion 9. The said spring pin at is provided with a large head adapted to-be operated from some moving part of the machine, say, the plunger Z which causes the boxes 0 to travel in the transverse portion 9 of the said trough. Or the said spring pin may be operated directly by means of a rod, lever or levers, and a cam, not shown in the drawings, but arranged in a similar manner to the lever and cam shown at Fig, 4, or cam and rod shown at Figs. 6 and 8. When the plunger Z is withdrawnstothe position shown at Fig. 12, the head of the spring pine: is withdrawn,by means of the attachment 1O fixed to the plunger Z coming in contact with the plate 11 on the outer end of the spring pin,w1thin the tube or carrier y. A box 0 at the end of the side oftrough b can then pass out of the longitudinal portion into its transverse portion 9. But when the plunger Z moves forward to traverse the boxes along the transverse portion 9 of the trough, as soon as the attachment 10 is clear of the piece 11 the spring pin at issues from its carrier y, as shown at Fig. 11, across the end'of the longitudinal portion of the trough b, and thus prevents a box 0 therein being pressed forward into a position to be acted upon by plunger Z.

Other parts of the machine, and the various operations for folding and closing the mouth of the bag, may be similar to those described in the aforesaid specification.

The action of the machine is as follows An open mouth bag made by hand or machinery with one end folded and closed is placed in one of the boxes 0 (Figs. 10 and 11) which are intermittently made to travel in the trough' bc The bag having been filled, shaken and stamped, it is then moved forward into position to b'e'acted upon by the block and folders 7', k. The f0 (1 5 is'first closedover the top of the contents of the bag by tli'eblock if havin been moved forward by cam u (Fig. 8), andwhile in this outward position the upstanding portions which forrn the folds 6, 7, (which are moved forward for .the purpose) are nipped and creased by the vertical inner portions of the folders 7', 70,.

against the sides of the block t: The said block is then withdrawn. The folders 1', ii,

are then moved forward respectively by the cams 0, p, and they are separately moved across the to of the contents of the bag for closing the fo ds 6 and 7 thereon. When the folder 7c has been moved into a similar posi- 1 tion in which folder-j is shown at Fig. '9, the inclined block a is, by its cam e and'leverf,

moved inwards to produce a nippin actionon fold 7 for preventin it afterwards flyingopen. The curved en s of the folders j,.k, are also employed during their said move- -ments for pressing the upstanding portion of fold 8 into the space between them and .0 and the partially close bag is then a ain made to travel forward with its back f0 (1 8.

still upstanding along the lon itudinal side or edge of the bar 111. The f0 ded portions 5, 6, 7, of the bagsimultaneously pass under. the bar. w (Fig. 11) which keeps the said -three folds closed until the box has passed into the end portion 9 of the trough'band has been acted upon by the plunger "Z for causing the box 0 to be brought under the end stamper 12. In order to prevent the iofo boxes 0 passing too quickly into the said end portion the spring stop so is arranged to be 0 erated by the plunger Z which 'is empoyed for intermittently operating the oxes c in the end portion 0' wardposition the spring stop a: will b the attachment "10 coming in contact wit ,the plate 11 cause the stop m'tobe withdrawn within the carrier y, and so allow a box etc the trough. When the plunger Z is withdrawn'to its outpass from the longitudinal portion of the trough 6 into its end ortion 9/; 'The box is then traversed along t e end portion 9- and as the upstanding'fold 8 is assed'nnder the end stamper 12 the said fol is closed onto the top of the contents of the bag by-the projection 13, and the fold 8 is finally presse and 5 creased by the end Stamper.
